LINQ, or Language-Integrated Query, is a feature of the .NET framework that enables developers to write queries against various data sources, such as databases, XML files, or in-memory data collections, using a uniform syntax and programming model.
With LINQ, developers can write queries using a familiar syntax that resembles SQL, and then execute those queries against any data source that implements the required interfaces. The LINQ query syntax is integrated into C# and other .NET languages, allowing developers to write queries directly in their code.
LINQ provides a wide range of operators, including filtering, sorting, grouping, aggregation, and more. These operators allow developers to manipulate data easily and efficiently.
Some benefits of using LINQ include improved code readability and maintainability, increased productivity, reduced coding errors, and improved performance due to efficient query execution.
LINQ has become a popular feature among .NET developers, and it is commonly used in various types of applications, from simple console applications to large-scale enterprise systems.
